As shown in Figs; 1 to 4, the lighting and extinguishing devicecomprises a clockwork movement a, onemovable part of which only is shownin Fig. 3. The spring,'not shown in the drawing, which operates-theclockwork in question, is arranged in the oar-rel 72, the spindle c ofwhich is constituted by the conduit admitting gas to the burner.

Specification of Letters Patent.

The circumference of the drum is provided with a kind of dial (Z dividedinto 24 hours; 12 hours for the day, and 12 hours for the night. On theupper face of the'barrel b are mounted two hands 0 f secured to andrendered integral with the barrel by means of a nut which neverthelesson being unscrewed enables the said hands to be moved independently ofeach other. The hands 0 f indicate, in fact, on the dial cl, onethe hourfor opening the burner, and the other-the closing hour. These hours canbe changed by moving the hands as just explained;

The spindle or gas conduit 0 and the 'clockwork a are stationary: whilethe barrel 12 rotates about the spindle 0. On the conduit 0 is mounted'a cock it provided with two holes 2' t" at 90. The plug of the saidcock is constituted by an eight-branched star 1',

other branches are the intermediate ones. The star in question isarranged in such manner that its branch which happens to be in thebottom position, meets the hands 6 f rotatingwith the barrel. The dial dis set so that the figure of the-dial d passing to the right of thebottom branch of the star j indicates the exact hour. A by-pass 7a whichreceives its gas at I from the conduit 0 in front of the cook it, isconstantly alight when the burner is extinguished. In these conditions,assuming that the burner is 'rovided with a by-pass and that thehand eindicates by its position on the dial d the hour for opening the burner,it will be understood that, when the ,hand in question arrives againstthe bottom branch of the star, it will move the latter to the extent ofone branch, which movement will be sutficient to bring the cock it fromthe closed position in which it was originally to the position in whichone of the openings z' or z" coincides with the" conduit 0. The gaspassing freely into the said conduit, goes to the burner and ignites oncontact with the flame of the by-pass which is then extinguished.

The hand 1 indicating by its position the hour of closing of the burner,will at that the star j which it will also move to the extent ofone-eighth of a revolution. In doing that, it will bring the cock intosuch position cide with the conduit 0, so that the burner v will beextinguished.

four branches of which correspond to thev two openings 6 c" whichintersect, while the precise moment strike the bottom branch of that theopenings 2' or 2" will no longer coin- A second lighting of the burnerwill take place exactly 2 hours after the first, unless the position ofthe hand c has been modified, by a new contact of the hand in questionwith the star i, extinguishing by means of the hand f.

The winding of the clockwork is effected simply by rotating the barrelZ).

The lightingand extinguishingdevice can be inclosed into a casing inthree parts on n 0, which will not in any way interfere with therotation of the cock, but will prevent on the contrary any fraudulenttampering with the device, the adjustment of the hands indicating theopening and closing, remaining in the hands of the person who has themeans for opening the casing in question.

The construction of the lighting and extinguishing device shown in Figs.5'9, has also a cloclnvork movement a, only one wheel of which is shownin Fig. 7. The spring, not. shown, which operates this clockwork isarranged in the barrel 0, the spindle r of which is constituted by theconduit used for the passage of the gas passing to the burner. ,1

A dial d divided into 21 hours as already described, occupies thecircumference of the barrel, on the .upper face of which are arrangedtwo hands c f, secured to the barrel by means of a nut g which onbeingunscrewed enables the hands in question to be moved independentlyof each other. Each of these hands is secured to a divided or split ringsurrounding. the central portion of the dial. The two ringscorresponding to the hands. are superposed on each other. By unscrewingthe nut, the rings will no longer be pressed against the dial arrangedabove the barrel, and owing to the slot with which each ring is providedand which gives the ring a certain play around the central portion ofthe dial, the two rings become absolutely independent of each other, andone of them may be rotated, without moving the other. When the two handsoccupy the desired position, the nut is again tightened and presses thetwo rings against the dial and fixes them, and'by this tightening thehands are caused to participate in the movement of the dial.

On the conduit 0 is mounted a cock it provided with one single opening2'. The spindle of this cock is provided at each of its ends 72 p with avertical finger or project-ion g g situated in the path of the 'hands 6Nevertheless the hand 0 which may be the opening hand, is provided witha projection e of such a length that it strikes the projection (1 butmisses the projection (1'. The hand 7'' is provided with a projection fwhich on the-contrary can strike the finger g and miss the finger g.

The cock 7! can oscillate to a certain extent, the said oscillation bemgproduced in one The same applies to the direction (opening) by thepassage of the hand 0 under the arm and in the other direction(closing). by the passage of the hand f under the arm 9. The opening andthe closing take place, therefore, as already described at 'given hours,by the suitable arrangement of the indicating hands on the dial.

A recess 1' made in the cock It, the Hat bottom of which carries ahollow cylindrical part which can more with slight amount of friction inthe extension 0 of the conduit, makes it possible, by the movement whichit gives to that part, to close the passage of the gas going to theburner, while leaving the passage for the gas going to the by-pass open.

In order to obtain the result in question, the sniall central tube twhich feeds the by-pass is provided at its bottonr end with a conicalthickened portion u to which corresponds a Ct'llllCtll recess of thepart 8. The cock being in the open position, there is between the cone uand the part a an empty space 1) through which the gas can pass into theburner. hem-however, the closing is brought about by the engagement ofthe arm'q with the hand f, and the cock It oscillates, the oscillationin question produces, as will be understood, the raising of the part swhich becomespressed against the cone u. I The passage 21 no longerexisting, and owing to the openings of the cock still communicating alittle with the conduit c, the slight quantity of gas supplied will passonly to the pipe t in order to feed the by-pass. i

\Vhen the cock it returns to the open posit-ion, the part- .9 is againlowered, and. the

' passage 0 again formed for admitting gas which becomes ignited at thetop of the burner on contact with the flame of the bypass.

This arrangement of the lighting and extinguishing device can also beprovided with a safety casing made for instance of three parts at n 0which will not in any way interfere with the rotation of thc cockbutwill, on the contrary, prevent. any fraudulent tampering with thedevice.

This invention relates also to the application of thesame device forbringing about the passage of current into an electric lamp andextinguishing the lamp in question at given hours which, however, can bemodified, or for the purpose of, after. having closed by hand thecircuit at any desired moment, automatically obtain the opening of thesame circuit after a certain period which can be regulated by the meanssupplied by the invention, and in that case the device can be used notonly for electric lighting, but also for working an audible signal orother apparat-us which are electrically disengaged.

.tion.

illustrate by way of example a device suitable for the said variousapplications.

The electric lighting and extinguishing device shown in Figs. 10 to 12employs the construction already described of the clockwork movement andof the spring operating the same, the clockwork being arranged at 1 andthe spring at 2 in the barrel, the spindle 3 of which is hollow in orderto afford passage to -the conductor wires et 4. The dial 5 and the hands6 (i are also similar to the construction previously described. Thewires st 4 suitably insulated in their passage through the spindle 3,terminate respectivel I at 7 7 in a block 8 of insulating material, theend of the said wires formingcontacts at 9 9. On the other hand, theoscillating part 10 carrying fingers 11 11 already described, receivesin a suitable recess a metal part 12 of a special shape which issuitably insulated from the said oscillating part.

The apparatus as described, is inserted into the circuit of the lamp orlamps the lighting and extinguishing of which at given hours it has tocontrol.

At the time of the extinction, the part 10 occupies the position shownin Fig. 12, in which the part .12 is moved away from the contacts 9 9and in which consequently the current cannot pass from 9 to 9. But atthe hour fixed for the lighting, the finger 11, for instance, is met bythe hand 6, the result of which is that the part- 10 is oscillated inthedirection of the arrow at (Fig. 12) and the part 12 comes intocontact with the contacts 9 9' (Fig. 10). The circuit of the lamp orlamps being closed on the said contacts, the lighting is obtained. Atthe hour fixed for the extinguishing, it is on the contrary the liu'ger1] which is met by the hand (3, and the part 19 oscillates in theopposite direc- The contact part 12 returns to the position shown inFig. 19.. and there is an interruption in the passage of current from 9to 9. The extingushing thus takes place. This arrangement of theelectric extinguishing and lighting device can also be inclosed in asafety casing 13 14 15 16 (Fig. 10) which does not in any way interferewith the oscillation of the part 10. but prevents any tampering with theclock.

\Vith the apparatus shown in Figs. 13 and 14, it is possible, by asimple manipulation, to bring about the lighting of a lamp or of aseries of electric lamps at once. and to de termine at the same time theperiod during which they are to remain alight. In order to make thething clear. it will be assumed that the apparatus plays the part of aswitch for one or more lamps lighting a staircase or passage. In thisconstruction, he spindle ot' the oscillating part 10 will merely beprovided with one finger It capable of engag ,ing with a projection 1Hdriven by the cioclc "work. when tln' apparatus is at zero, that returnof the is to say, when it is not wound up, the projection 18 is incontact with the finger 11 which is pushed back, and the part 10 is inthe position shown in Fig. 14, in which the contact part 12 isdisengaged from the contacts 9 9. That is, therefore, the period ofextinguishing of the lamp or lamps. If itis desired to light the lampfor going down the staircase or passing the passage, it is sufticient toturn the dial 5 in the suitable direction. The projection 18 will atonce release the finger 11, and owing to the action of a spring 19mounted under a cap 17, the part 10 will oscillate in the direction ofthe arrow a, (Fig. in such manner that the part 12' will establishcontact between 9 and 9. The lamp or lamps will then be lighted. But. onturning the dial 5, the period of lighting has been determined byplacing a division'of the said dial in front of an index 20 which innormal times indicates the zero. It, therefore, the dial has been movedto the extent of two divisions of 5 minutes each, the apparatus has beenwound for 10 minutes, and the lamps will be automatically extinguishedat the end of that period of time, asthe dial will return at that momentto the zero, and the projection 18 to contact with the finger 11, theresult of which will be the part 10 to the position shown in F ig. 14.

The same apparatus, and more particularly the construction shown in Fig.10, could also be utilized for ringing an electric bell and anyelectrically released apparatus which has to work for given periods oftime, whether variable or invariable.

vln a device for automatically lighting and extinguishing gas burners atgiven hours. the combination, of a burner 'ith the'pipe supplying gas tothe burner, of a clock movement the barrel of which is mounted to rotateabout saidpipe as a spindle. a cock arranged to oscillate, anintermediate part.

adapted to be raised and lowered by lh oscillation of said cock forclosing and opcning a passage for the gas going to the burner, fingerscarried by said cock, hands adjustahly mounted on the barrel of theclock movement for indicating the hours of lighting and extinguishingand provided with projections adapted to engage the respective fingerson said cock whereby the feeding of gas to the burner is automaticallycontrolled as desired, and a small pipe supplying a bypass which remainsconstantly in communication with the gas supply pipe.

In testimony whereof I have si ned this specification in the presence oftwo subscribing witnesses.
